Double stranded RNA and the nuclear matrix--implications for the 2-5A system.

Abstract

RNA species present on rat liver nuclear matrices were investigated. Nuclear matrices prepared by extensive digestion of isolated nucleii with DNase and RNaseA followed by low and high (2M NaC1) salt washes were labelled in vitro with T4 RNA ligase and [5'-32P]pCp and the labelled RNA analysed by gel electrophoresis. Despite the extensive RNaseA treatment… (More)
